Electric Discharge Machine > M Series Seibu made the world’s first CNC wire Electrical Discharge Machine (EDM) in 1972. With a fine and silky smooth motion, an electrode wire can cut metal as desired. Our new, innovative technique for high-quality, high-precision cutting is based on the pride in our craftsmanship that has made those characteristics bywords in our company and representative of our products. Seibu will continue to take that extra step in EDM manufacturing to provide our valued customers with innovations and quality arising from the combination of traditional technique and advanced technologies. An annealing current is repeatedly passed through the wire, and the wire is pulled while being heated to straighten it using our dry annealing method. This assures the automatic feeding at wire break point nearly 100%. (Patented in Japan, Europe, and the USA) Top-class AWF (Automatic Wire Feeding Device) supports non-stop operation and greatly improves operation rate. Newly developed corner control (TC control) is provided as standard, which realizes better cutting accuracy and surface finish compared with conventional system. For the improved operability that is essential for all machines,the design must be simple and easy to understand. Touch panel gives any operator easy operation such as input of cutting conditions, plotting, and so on. Ana-ake Taro (attachment) is a start-hole drill that can be mounted on all models easily. This can variously help any users in start hole drilling.
